The aim of this pilot study is to examine a brief manualized treatment, Emotional Regulation Group Skills Training (ERG ST), which has shown promise with high-risk youth presenting with a range of mental health concerns. The investigators will examine the effectiveness of a ERG ST group, as well as two additional components to which clients will be randomized: a motivational enhancement (ME) pre-treatment, and family skills treatment (FAM). This project will be the first to combine and test these modules as a transdiagnostic early intervention for youth in the early stages on mental illness. This pilot trial will answer the following questions: 1) What is the response rate to ERG ST compared to ERG ST plus FAM, and who benefits? 2) What is the response rate to a ME pre-treatment, and who benefits? 3) What is the acceptability of this treatment?

The ME pre-treatment will consist of four weekly one and a half hour sessions. The 12-week ERG ST will consist of 12 weekly two-hour sessions with 4-12 youths per group. The 12-week FAM will consist of 12 weekly two-hour sessions, with 16-20 caregivers per group. This study will use a two-stage randomization design to allow for balanced groups if there is differential attrition after pre-treatment. The following are the four treatment combinations: ERG ST; ERG ST+FAM; ME+ERG ST; ME+ERG ST+FAM. Four subjects will be enrolled in the study and randomized. The primary outcome is to improve emotion dysregulation in participants. Emotion dysregulation will be measured using the Difficulties in Emotion Regulation Scales (DERS).

Change from Baseline in Emotion Regulation throughout 12-week ERG group, at post ERG group and 16-week follow-up to group. [ Time Frame: Baseline (2 weeks pre-ERG ST), Weeks 1, 4, 9 and 12 of ERG ST and 12 weeks after the end of ERG ST ]

The Difficulties in Emotion Regulation Scales is a 36-item self-report measure of emotion dysregulation with adequate psychometric properties.

The GAIN-Q3-MI-ONT includes the following scales: School Problems, Work Problems, Health Problems, Sources of Stress, Risk Behaviours, Internalizing Disorders, Externalizing Disorders, Substance Disorders, Crime & Violence and Total Disorder. For most individual screeners, internal consistency is good to excellent (alpha > .7) for adolescents and adults.

The Depression Anxiety and Stress Scales 21 (DASS-21) is a 21-item short-form measure of depression, anxiety and stress. Reliability, measured using Cronbach's alpha, has been shown to be adequate: alpha = .93 for the total scale. The DASS-21 has shown good convergent and discriminant validity when compared with other measures of depression and anxiety.

The Burden Assessment Scale, which assesses levels of objective and subjective burden, and the Perceived Burden Scale, which assesses interpersonal burden and role strain, will be used as a measure of caregiver burden.

The L-SASI is an interview to collect lifetime history details of non-suicidal self-injury and suicidal behaviour. The interview will be used to exclude individuals who have had moderate to severe self-harm within the past year.

This is a brief structured interview for the major psychiatric disorders in the DSM. It assesses for: major depressive episode, suicidality, manic episode, bipolar disorders, panic disorder, agoraphobia, social phobia, obsessive-compulsive disorder, posttraumatic stress disorder, alcohol abuse and dependence, substance use and dependence, psychotic disorders, anorexia nervosa, bulimia nervosa, generalized anxiety disorder. The M.I.N.I. will be used to ensure that exclusion criteria are not being met.

A selection of questions from the B-THI that contains face-valid questions will be used to assess for hospitalization and psychiatric emergency use, psychotropic medication and receipt of ancillary psychotherapy.

FAD is a 53 item self-report measure designed to measure family function (31). The FAD is made up of seven scales which measure Problem Solving, Communication, Roles, Affective Responsiveness, Affective Involvement, Behaviour Control and General Functioning. The reliability, measured using Cronbach's alpha, ranged from 0.72 (Roles and Behaviour Control) to 0.92 (General Functioning).

The Adult Behaviour Checklist for ages 18-59 (ABCL) is a checklist used to obtain information on a range of mental health and substance use concerns. The family/friends will report on the youth's difficulties. Authors report internal consistency alphas ranging from 0.78 to 0.85 and test-retest reliability ranging from r = 0.73-0.92.
